14. Is Blood Pressure the Same for Both Arms? Listed below arc systolic blood pressure measurements (mm Hg) taken from the right and left arms of the same woman (based on data from “Consistency of Blood Pressure Differences Between the Left and Right Arms,” by Eguchi, et al., Archives of Internal Medicine, Vol. 167). Use a 0.01 significance level to test for a difference between the measurements from the two arms. What do you conclude?

If the average of the data set given below as a missing ('*') value is 7.5, calculate the Q1 (lower quartile) value for this set.

Listed below are systolic blood pressure measurements (mm Hg) taken from the right and left arms of the same woman. Assume that the paired sample data is a simple random sample and that the differences have a distribution that is approximately normal. Use a 0.01 significance level to test for a difference between the measurements from the two arms. What can be concluded?

Cholesterol The level of cholesterol in the blood for all men aged 20 to 34 follows a Normal distribution with mean 188 milligrams per deciliter (mg/dl) and standard deviation 41 mg/dl. For 14-year-old boys, blood cholesterol levels follow a Normal distribution with mean 170 mg/dl and standard deviation 30 mg/dl. Suppose we select independent SRSs of 25 men aged 20 to 34 and 36 boys aged 14 and calculate the sample mean cholesterol levels M and XB. What is the shape of the sampling distribution of XM - XB? Why? Find the mean of the sampling distribution. Show your work. Find the standard deviation of the sampling distribu- tion. Show your work.
